If one were to judge by the new product introductions from Ayre and Jeff Rowland Design, $18k seems to be the price point for high-end solid-state preamplifiers. Rowland's new Criterion preamp uses NiMH batteries in the power supply; these are more easily available than the lead-zinc ones that were used in Rowland's previous top preamp—and, of course, the design of the Criterion features a number of improvements from its predecessor. Rowland also introduced the new Continuum integrated amp, available in two version: 350Wpc ($7200) or 500Wpc ($8800), the latter featuring power-factor correction.
